Description

【０００１】
【発明の属する技術分野】
本発明は、各種機器製品で行なわれている、粘着剤によって貼り付けられた部品やラベルなど貼付部材を自動的に剥離する貼付部材剥離装置に関する。
【０００２】
【従来の技術】
電子写真技術を用いた画像形成装置においては、画像を形成させる現像部周辺の部材に、トナーの漏れ防止用としてウレタン発泡体、モルトプレーン、フエルトなどが数多く使用されている。これらの部材は粘着剤で固定されていることが多く、再使用するためには貼り付けられている部材の分解・分別が必要不可欠となる。
このような分解・リサイクル工程において、粘着剤により被貼付部材に固定された貼付部材を剥がす作業は、比較的長い作業時間を要し、作業者の爪や指先に負担を強いる作業である。そのため、これら作業を自動化することが従来より望まれている。
通常、人が作業する場合、図１９に示したように貼付部材Ｍの端部をつかんで引っ張る。この場合、図１９から明らかなように、貼付部材Ｍの端部を、その貼付部材Ｍの長さの２倍の距離を移動させる必要がある。したがって、自動機械で同様の動作を行わせた場合、長尺部材になるほど装置が大型化するし、動作所要時間が長くなる。また、貼ってから長年経過した粘着テープは剥離性が悪く、剥がし途中でちぎれる場合があり、人が作業する場合にも問題となっている。自動機械に人と同様の剥離動作を行わせた場合、ちぎれた端部を検出してつかみ直すなどの複雑な動作や認識制御が必要となり、高価な設備になるおそれがある。その上、長年経過した粘着テープでは、剥がした後に粘着剤の糊残りが発生することがあり、部品のリサイクル工程では粘着剤の除去が課題となっている。
なお、従来より、剥離紙、セパレータ、保護フィルムなどを剥離する技術は数多く提供されている。例えば、特開平１０−３１６３０３号公報に示された従来技術では、吸引保持手段を利用して剥離紙を剥離する。また、特公平６−９９０７５号公報に示された従来技術では、円錐状フィルムスクラッチャーおよび流体吹きつけ力を利用してフィルムを剥離する。また、特許第２６８０９６７号公報に示された従来技術では、対向する粘着ゴムローラを用いてマイラフィルムを剥離する。
【０００３】
さらに、特開平１０−２８２４６３号公報に示された従来技術では、粘着フィルムの一辺全体を剥離ローラに挟み、強固に固定した後、剥離ローラを回転機構で回転させながら被接着体を移動させて、剥離ローラの外周に粘着フィルムを巻き付けて剥離を行う。この方法によれば、粘着フィルムの一辺を剥離ローラのクランプ機構により固定するので、粘着フィルムの粘着力の強弱に左右されることなく、粘着フィルムを確実に剥離できる旨がうたわれている。
また、特開平７−２１５５７７号公報や特開平１１−２５８９９８号公報に示された従来技術では、貼付に、加熱により粘着力が低下する粘着剤層を備えた両面粘着テープを用いる。
【０００４】
【発明が解決しようとする課題】
しかしながら、上述した特開平１０−３１６３０３号公報、特公平６−９９０７５号公報、特許第２６８０９６７号公報に示された従来技術では、粘着剤によって強固に固定されている貼付部材を剥離する場合は、粘着力が強いので、提案されているような方法で貼付部材を剥離することは難しい。また、特開平１０−２８２４６３号公報に示された従来技術では、予め剥がし治具によって粘着フィルムの一辺全体を所定量引き剥がした状態にすることが必要であるので、人手作業の負担が大きい。また、特開平７−２１５５７７号公報や特開平１１−２５８９９８号公報に示された従来技術では、特殊な粘着剤を用いるのでコストが高くなるし、温度条件上すべての貼付部材に使用できないといった問題がある。
従って、本発明の目的は、粘着剤によって固定された貼付部材を効率よく確実に剥離することができる貼付部材剥離装置を提供することにある。
【０００５】

【０００７】
【発明の実施の形態】
以下、図面により本発明の実施の形態を詳細に説明する。
〔第１の実施の形態〕
図１は本発明の第１の実施の形態を示す貼付部材剥離装置の構成図である。（ａ）は側面図、（ｂ）は平面図であり、この実施の形態の貼付部材剥離装置（以下、剥離装置と略す）とともに、粘着剤によって被貼付部材Wに貼り付けられている貼付部材Ｍの一部が剥離された状態を示している。
図示したように、第１の回転部材（以下、単に回転部材と略す）１およびＡギア４は共通の軸７を持ち、一体となって回転する。第２の回転部材である補助ローラ２およびＢギア５も共通の軸８を持ち、一体となって回転する。また、軸７および軸８はそれぞれ支持フレーム１０に回転自在に取り付けられ、その支持フレーム１０には、駆動モータ９および中間ギア６の軸も固定されている。この中間ギア６は中間ギア軸を軸として回転自在であり、駆動ギア３およびＢギア５と噛み合っている。
また、回転部材１と補助ローラ２間には、所定量（貼付部材Ｍの厚みよりやや狭い）のギャップが存在する。さらに、各ギアの歯数比は回転部材１と補助ローラ２の周速が等しくなるように調整されている。
また、回転部材１の表面には、貼付部材Ｍの先端をめくりやすくするための突起状物１１を設けている。突起状物１１の形状としては、ピン形状（図２参照）、フィン（羽根板）形状（図３参照）、ブラシ毛形状（図１１参照）などが可能である。
前記突起状物１１の突起の方向は回転部材１の回転方向を向いている方が貼付部材Ｍの先端をめくるのに適している。具体的には、根元から斜めに固定したり（図９参照）、突起状物１１ｃの先端が回転方向を向くようにカールさせたりする（図４参照）。
貼付部材Ｍの先端をめくりやすくする方法として、突起に引っかかり構造を持たせることも可能である。図５に示したような鉤状突起状物１１ｄ、図６に示したような錨状突起状物１１ｅ、図７に示したような複数の引っかかり部を持つ形状の突起状物１１fなどが可能である。
【０００８】
また、図８に示したように、繊維１６に顆粒１７を接着して引っかかり構造を持たせることも可能である。
突起状物を交換可能な構造にすることも可能である。摩擦による消耗や変形などが発生した場合に備え、容易に交換可能にするのが望ましいのである。具体的には、図９に示したように、突起板１１ｈを固定片１８で押さえて固定する（ネジ止めやスナップフィット）。または、図１０に示したように、突起付シート１４を芯金ローラ１３に巻きつける構造にすることにより突起付きシート１４を交換する。図示したように、突起付きシート１４の突起面１５に、多数の突起状物１１を備えておく。
また、突起状物の材質は被貼付部材Ｗの材質や剥離後の貼付部材Ｍの用途に合わせて適切に選定する。つまり、被貼付部材Ｗに深い傷をつけてはならない場合は、突起状物を被貼付部材Ｗより硬度の低い材質で構成する。
また、当該剥離対象の貼付部材Ｍの大きさや当該被剥離対象の被貼付部材Wの形状に応じて、適切な幅と径の回転部材１を軸ごと交換可能にしている。
また、回転部材１が被貼付部材Ｗおよび貼付部材Ｍに当接した際、回転部材１または突起状物が弾性変形するように回転部材１または突起状物の材質を選定する。なぜならば、弾性変形することにより、剥離装置を被貼付部材Ｗに押し付けても、突起状物や被貼付部材Ｗに過大な力が加わることを防止できるので、剥離装置の位置決め精度をそれほど高精度にする必要がなくなるからである。
このような構成で、本発明の第１の実施の形態では、図１に示したように、駆動ギア３が例えば反時計回り（矢印の方向）に回転することにより、Ａギア４および回転部材１が時計方向（矢印の方向）に回転するとともに中間ギア６が時計方向（矢印の方向）に回転し、それによりＢギア５および補助ローラ２が反時計回り（矢印の方向）に回転する。つまり、回転部材１と補助ローラ（第２の回転部材）２とは互いに逆向きに回転する。
【０００９】
以下、図１１〜図１６などに従って、回転部材１の回転動作により貼付部材Ｍを剥離する動作を説明する。
まず、回転部材１が、その表面の突起状物１１ｇが被貼付部材Wの先端に接する位置に移動する（図１１）。そして、矢印で示す方向に回転する突起状物１１gにより、被貼付部材Wの先端が剥離される（図１２）。さらに、剥離装置が左方に移動することにより、剥離が進行する（図１３）。
同様にして剥離が進み（図１４）、やがて、貼付部材Ｍは回転部材１と補助ローラ（第２の回転部材）２の間に挟まれる（図１５，図１６）。回転部材１と補助ローラ２の間に貼付部材Ｍを挟みこむのを助けるため、補助ローラ２の表面にも突起を設けてもよい。
この後、剥離装置を図のさらに左方向へ移動させることにより貼付部材Ｍ全体を剥離することができる。
剥離装置の移動距離は貼付部材Ｍの長さ程度であり、移動距離が貼付部材Ｍの長さの２倍ほどになる従来技術に比べれば、効率よく短時間に剥離することができる。回転部材１と補助ローラ２とによるクランプ送り力と回転部材１によるめくり力の両方が貼付部材Ｍに作用するので、貼付部材Ｍが切れにくい。また、貼付部材Ｍが途中で切断した場合でも、図１１〜図１５のいずれかの状態になるので、そのまま剥離動作を続行することができる。また、粘着剤の一部が被貼付部材Ｗ上に残っていたとしても、回転部材１の突起状物がその表面をこすりながら移動するので、残っている粘着剤は掻き取られてしまう。
こうして、この実施の形態によれば、第１の回転部材の回転により貼り付けられている貼付部材の端部をめくり起こし、その回転部材と第２の回転部材との間に貼付部材を挟んで被貼付部材から剥離するので、粘着剤によって固定された貼付部材を効率よく確実に剥離することができる。
また、第１の回転部材の表面に、例えば、先端がその回転部材の回転方向を向いた突起状物を形成しているので、貼付部材の端部が確実にめくり起こされる。また、突起状物が引っかかり構造を有している構成では、突起状物の先端を貼付部材端部に引っ掛けてめくり起こすことができる。また、突起状物の材質を被貼付部材に比べて硬度の低い材質にした構成では、被貼付部材に傷をつけないで済む。
また、第１の回転部材または突起状物を弾性体にした構成では、剥離装置の位置決め精度をそれほど高精度にする必要がなくなる。
また、第１の回転部材表面の突起状物を交換可能にした構成では、突起状物の消耗に対処できるし、対象となる貼付部材や被貼付部材に応じて適切な突起状物に交換することができる。
また、第１の回転部材を交換可能にした構成では、対象となる貼付部材や被貼付部材に応じて適切な回転部材に交換することができる。
【００１０】
〔第２の実施の形態〕
図１７は、本発明の第２の実施の形態を示す貼付部材剥離装置の構成図である。（ａ）は側面図、（ｂ）は平面図であり、この実施の形態の剥離装置とともに、粘着剤によって被貼付部材Ｗに貼り付けられている貼付部材Ｍの一部が剥離された状態を示している。図示したように、この実施の形態の剥離装置は第１の回転部材が帯状の構成である。なお、第１の回転部材表面の突起の構造・形状などについては、第１の実施の形態で説明したようなさまざまなバリエーションが同様に実施可能である。
図１７に示したように、第１の回転部材である剥離ベルト２０は駆動ローラ２３および先端ローラ２１とともに巻きつけ伝動系を形成している。また、補助ローラ２２が補助ローラ軸２７を中心として回転自在に固定され、その補助ローラ軸２７および分離ピン３１が揺動アーム３０に固定されている。この揺動アーム３０は揺動軸２８を中心として揺動し、図示しないバネなどにより図中に矢印で示した付勢方向に付勢されている。また、先端ローラ２１の回転軸である先端ローラ軸２５、駆動ローラ２３の回転軸である駆動ローラ軸２６、および揺動軸２８が支持フレーム２９に回転自在に固定され、その支持フレーム２９は、図示しない移動手段（垂直多関節ロボットなど）によって移動される。なお、この剥離装置を工具として作業者が使用する場合は、支持フレーム２９に持ち手をつけて作業をしやすくしてもよい。また、剥離ベルト２０や先端ローラ２１は交換可能に構成されており、対象の被貼付部材Ｗの形状および貼付部材Ｍの大きさや厚みなどが異なる場合、剥離ベルト２０の幅や先端ローラ２１の径などを適切に変えて対応する。
【００１１】
以下、この実施の形態の動作を説明する。
まず、駆動モータ３２により、駆動ローラ２３が回転し、剥離ベルト２０が回転する。このとき、剥離ベルト２０に接している補助ローラ２２は剥離ベルト２０の回転によって連れ回りする。こうして、剥離ベルト２０の表面の突起状物２４が貼付部材Ｍの端部に接触する位置に移動し、貼付部材Ｍを剥離していく。第１の実施の形態と同様に、剥離装置全体が図の左方向に移動するにつれて、剥離ベルト２０と補助ローラ２２との間に挟まれた貼付部材Ｍが被貼付部材Ｗから剥離されるのである。
前記剥離動作において、貼付部材Ｍが剥離ベルト２０にくっついていた場合には、分離ピン３１にぶつかって分離される。なお、剥離ベルト２０および分離ピン３１は貼付部材Ｍの粘着面と接するので、表面を非粘着加工とする。具体的には、ＰＴＦＥ、ＰＦＡなどのフッ素コーティングが望ましい。または、フッ素系樹脂そのもので分離ベルト２０の突起状物２４を形成してもよい。
こうして、この実施の形態によれば、第１の回転部材が帯状体であることにより、第１の回転部材の周長を長くとれるので、消耗寿命が長くなり、交換頻度が少なくて済む。また、交換作業性も容易である。さらに、先端ローラを交換することで、第１の回転部材の先端の曲率半径を変化させて対象部材に対応することができる。
【００１２】
〔第３の実施の形態〕
本発明の第３の実施の形態では、剥離装置の移動を自動で行う場合、回転部材の回転抵抗を検出する。回転抵抗を検出するには、例えば、
▲１▼駆動モータの電流を検出する、
▲２▼先端ローラの回転数を検出する、
▲３▼駆動ローラと先端ローラの回転数の比や差を検出する、
などの方法による。
図１８は、横軸に時間、縦軸に回転抵抗をとって回転抵抗の変化例を示したものである。このようにして回転抵抗を検出し、その回転抵抗から第１の回転部材と貼付部材Ｍとの接触状態や先端の剥離状態を検出することができるので、それを利用して駆動モータの回転数を制御したり、剥離装置を移動させる移動手段を制御したりすることが可能になる。
また、途中で貼付部材Ｍが切断してしまった場合も、回転抵抗の変化から検出できる。剥離装置の移動速度と切断率の関係を利用して、前記移動手段を適切な速度に制御することもできる。
【００１３】
【発明の効果】

即ち、請求項１記載の発明によれば、隣接した第１の回転部材と第２の回転部材とが互いに逆方向に回転し、第１の回転部材の回転により、貼り付けられている貼付部材の端部がめくり起こされ、第１の回転部材と第２の回転部材との間に貼付部材が挟まれ、二つの回転部材が回転しながら貼付部材に沿って進むことにより、貼付部材が被貼付部材から剥離されるので、粘着剤によって固定された貼付部材を効率よく確実に剥離することができる。

また、請求項９記載の発明によれば、請求項２、請求項３、または請求項４記載の発明において、第１の回転部材表面の突起状物を交換することができるので、突起状物の消耗に対処できるし、第１の回転部材を再使用することが可能になり、資源の有効活用につながる。

BACKGROUND OF THE INVENTION
The present invention relates to a sticking member peeling device that automatically peels sticking members such as parts and labels attached with an adhesive, which are performed in various equipment products.
[0002]
[Prior art]
In an image forming apparatus using an electrophotographic technique, urethane foam, malt plain, felt, and the like are often used as members around a developing unit for forming an image to prevent toner leakage. These members are often fixed with an adhesive, and in order to reuse them, it is essential to disassemble and separate the pasted members.
In such a disassembling / recycling process, the work of peeling the sticking member fixed to the sticking member with the adhesive requires a relatively long working time and imposes a burden on the operator's nails and fingertips. Therefore, it has been desired to automate these operations.
Normally, when a person works, the end of the sticking member M is grasped and pulled as shown in FIG. In this case, as is apparent from FIG. 19, it is necessary to move the end portion of the sticking member M by a distance twice as long as the length of the sticking member M. Therefore, when the same operation is performed with an automatic machine, the longer the member, the larger the apparatus and the longer the time required for the operation. Moreover, the adhesive tape which passed many years after sticking has bad peelability, and may be torn off in the middle of peeling, and it is also a problem when a person works. When the automatic machine performs a peeling operation similar to that of a human, complicated operation such as detecting a broken edge and re-gripping it is necessary, which may result in expensive equipment. In addition, adhesive tape that has been used for many years may cause adhesive residue after peeling, and removal of the adhesive is an issue in the part recycling process.
Conventionally, many techniques for peeling release paper, separators, protective films and the like have been provided. For example, in the prior art disclosed in Japanese Patent Application Laid-Open No. 10-316303, the release paper is peeled off using a suction holding means. In the prior art disclosed in Japanese Patent Publication No. 6-99075, the film is peeled off using a conical film scratcher and a fluid blowing force. In the prior art disclosed in Japanese Patent No. 2680967, the mylar film is peeled off using an opposing adhesive rubber roller.
[0003]
Further, in the prior art disclosed in Japanese Patent Application Laid-Open No. 10-282463, after the entire side of the adhesive film is sandwiched between the peeling rollers and firmly fixed, the adherend is moved while the peeling roller is rotated by a rotation mechanism. Then, an adhesive film is wound around the outer periphery of the peeling roller to perform peeling.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[First Embodiment]
FIG. 1 is a configuration diagram of a sticking member peeling device showing a first embodiment of the present invention. (A) is a side view, (b) is a plan view, and affixing member that is affixed to a to-be-adhered member W with an adhesive together with the affixing member peeling device (hereinafter referred to as a peeling device) of this embodiment A part of M is peeled off.
As shown, the first rotating member (hereinafter simply referred to as a rotating member) 1 and the A gear 4 have a common shaft 7 and rotate together. The auxiliary roller 2 and the B gear 5 as the second rotating member also have a common shaft 8 and rotate together. Further, the shaft 7 and the shaft 8 are rotatably attached to the support frame 10, and the shafts of the drive motor 9 and the intermediate gear 6 are also fixed to the support frame 10. The intermediate gear 6 is rotatable about the intermediate gear shaft and meshes with the drive gear 3 and the B gear 5.
Further, a predetermined amount of gap (slightly narrower than the thickness of the sticking member M) exists between the rotating member 1 and the auxiliary roller 2. Further, the gear ratio of each gear is adjusted so that the peripheral speeds of the rotating member 1 and the auxiliary roller 2 are equal.
Further, a protrusion 11 is provided on the surface of the rotating member 1 so that the tip of the sticking member M can be easily turned. As the shape of the protrusion 11, a pin shape (see FIG. 2), a fin (blade) shape (see FIG. 3), a brush bristle shape (see FIG. 11), and the like are possible.
The direction of the protrusion of the protrusion 11 is suitable for turning the tip of the sticking member M so that the rotation direction of the rotating member 1 is directed. Specifically, it is fixed obliquely from the root (see FIG. 9), or is curled so that the tip of the projection 11c faces the rotation direction (see FIG. 4).
As a method for making it easier to turn the tip of the sticking member M, it is possible to catch the protrusion and give it a structure. A hook-like protrusion 11d as shown in FIG. 5, a hook-like protrusion 11e as shown in FIG. 6, and a protrusion 11f having a plurality of hooks as shown in FIG. 7 are possible. It is.
[0008]
Further, as shown in FIG. 8, it is also possible to attach a granule 17 to the fiber 16 to give it a hooked structure.
It is also possible to make the protrusions have a replaceable structure. It is desirable that it can be easily replaced in case of wear or deformation due to friction. Specifically, as shown in FIG. 9, the protruding plate 11h is pressed and fixed by the fixing piece 18 (screwing or snap fitting). Alternatively, as shown in FIG. 10, the protrusion-equipped sheet 14 is replaced by a structure in which the protrusion-provided sheet 14 is wound around the core metal roller 13. As shown in the drawing, a large number of protrusions 11 are provided on the protrusion surface 15 of the sheet 14 with protrusions.
Further, the material of the protrusion is appropriately selected according to the material of the member W to be pasted and the application of the pasting member M after peeling. That is, when the to-be-bonded member W should not be deeply damaged, the protrusion is made of a material having a hardness lower than that of the to-be-bonded member W.
Further, the rotating member 1 having an appropriate width and diameter can be exchanged in accordance with the size of the sticking member M to be peeled and the shape of the sticking member W to be peeled.
In addition, when the rotating member 1 comes into contact with the member to be pasted W and the pasting member M, the material of the rotating member 1 or the projecting object is selected so that the rotating member 1 or the projecting object is elastically deformed. This is because, by elastically deforming, even if the peeling device is pressed against the adherend member W, it is possible to prevent an excessive force from being applied to the protrusions and the adherend member W, so that the positioning accuracy of the peeler is very high. It is because it is not necessary to make it.
With such a configuration, in the first embodiment of the present invention, as shown in FIG. 1, when the drive gear 3 rotates, for example, counterclockwise (in the direction of the arrow), the A gear 4 and the rotating member 1 rotates clockwise (in the direction of the arrow) and the intermediate gear 6 rotates in the clockwise direction (in the direction of the arrow), whereby the B gear 5 and the auxiliary roller 2 rotate counterclockwise (in the direction of the arrow). That is, the rotating member 1 and the auxiliary roller (second rotating member) 2 rotate in opposite directions.
[0009]
Hereinafter, the operation of peeling the sticking member M by the rotating operation of the rotating member 1 will be described with reference to FIGS.
First, the rotating member 1 moves to a position where the projection 11g on the surface thereof is in contact with the tip of the member W (FIG. 11). And the front-end | tip of the to-be-bonded member W is peeled by the projection-shaped object 11g which rotates in the direction shown by the arrow (FIG. 12). Further, the peeling proceeds by moving the peeling device to the left (FIG. 13).
In the same manner, peeling progresses (FIG. 14), and the sticking member M is eventually sandwiched between the rotating member 1 and the auxiliary roller (second rotating member) 2 (FIGS. 15 and 16). In order to help sandwich the sticking member M between the rotating member 1 and the auxiliary roller 2, a protrusion may be provided on the surface of the auxiliary roller 2.
Thereafter, the entire sticking member M can be peeled by moving the peeling device further leftward in the figure.
The moving distance of the peeling device is about the length of the sticking member M, and can be peeled efficiently and in a short time as compared with the conventional technique in which the moving distance is about twice the length of the sticking member M. Since both the clamp feed force by the rotating member 1 and the auxiliary roller 2 and the turning force by the rotating member 1 act on the sticking member M, the sticking member M is difficult to cut. Moreover, even if the sticking member M is cut in the middle, the state becomes any one of FIGS. 11 to 15, so that the peeling operation can be continued as it is. Even if a part of the adhesive remains on the adherend member W, the protrusion of the rotating member 1 moves while rubbing the surface, so that the remaining adhesive is scraped off.
Thus, according to this embodiment, the end of the sticking member attached by the rotation of the first rotating member is turned up, and the sticking member is sandwiched between the rotating member and the second rotating member. Since it peels from a to-be-bonded member, the sticking member fixed with the adhesive can be peeled efficiently and reliably.
In addition, since, for example, a protruding object whose tip is directed in the rotation direction of the rotating member is formed on the surface of the first rotating member, the end of the sticking member is reliably turned up. Further, in the configuration in which the protrusion has a catching structure, the tip of the protrusion can be hooked on the end of the sticking member and turned up. Further, in the configuration in which the material of the protrusion is made of a material having a lower hardness than that of the member to be bonded, it is not necessary to damage the member to be bonded.
Further, in the configuration in which the first rotating member or the protrusion is an elastic body, it is not necessary to make the positioning accuracy of the peeling device so high.
Further, in the configuration in which the protrusions on the surface of the first rotating member can be replaced, the consumption of the protrusions can be dealt with, and the protrusions can be replaced with appropriate protrusions depending on the target sticking member and the member to be stuck. be able to.
Moreover, in the structure which made the 1st rotation member replaceable, it can replace | exchange for an appropriate rotation member according to the sticking member used and the to-be-pasted member.
[0010]
[Second Embodiment]

Show. As shown in the figure, in the peeling device of this embodiment, the first rotating member has a band-like configuration. It should be noted that various variations as described in the first embodiment can be similarly implemented for the structure and shape of the protrusions on the surface of the first rotating member.
As shown in FIG. 17, the peeling belt 20 as the first rotating member is wound together with the driving roller 23 and the tip roller 21 to form a transmission system. The auxiliary roller 22 is fixed to be rotatable about the auxiliary roller shaft 27, and the auxiliary roller shaft 27 and the separation pin 31 are fixed to the swing arm 30. The swing arm 30 swings about the swing shaft 28 and is biased in a biasing direction indicated by an arrow in the drawing by a spring or the like (not shown). Further, a tip roller shaft 25 that is a rotation shaft of the tip roller 21, a drive roller shaft 26 that is a rotation shaft of the drive roller 23, and a swing shaft 28 are rotatably fixed to a support frame 29. It is moved by a moving means (not shown) such as a vertical articulated robot. In addition, when an operator uses this peeling apparatus as a tool, a handle may be attached to the support frame 29 to facilitate the work. In addition, the peeling belt 20 and the leading roller 21 are configured to be replaceable, and when the shape of the target member W and the size and thickness of the sticking member M are different, the width of the peeling belt 20 and the diameter of the leading roller 21 are different. Change it appropriately.
[0011]
Hereinafter, the operation of this embodiment will be described.
First, the drive roller 32 is rotated by the drive motor 32, and the peeling belt 20 is rotated. At this time, the auxiliary roller 22 in contact with the peeling belt 20 is rotated by the rotation of the peeling belt 20. Thus, the protrusion 24 on the surface of the peeling belt 20 moves to a position where it contacts the end of the sticking member M, and the sticking member M is peeled off. As in the first embodiment, the sticking member M sandwiched between the peeling belt 20 and the auxiliary roller 22 is peeled from the sticking member W as the entire peeling device moves in the left direction in the figure. is there.
In the peeling operation, when the sticking member M is stuck to the peeling belt 20, it hits the separation pin 31 and is separated. In addition, since the peeling belt 20 and the separation pin 31 are in contact with the adhesive surface of the sticking member M, the surface is made non-adhesive. Specifically, fluorine coating such as PTFE and PFA is desirable. Alternatively, the protrusions 24 of the separation belt 20 may be formed of the fluororesin itself.
Thus, according to this embodiment, since the first rotating member is a belt-like body, the circumferential length of the first rotating member can be increased, so that the wear life is increased and the replacement frequency can be reduced. Also, the replacement workability is easy. Furthermore, by changing the tip roller, the radius of curvature of the tip of the first rotating member can be changed to correspond to the target member.
[0012]
[Third Embodiment]
In the third embodiment of the present invention, when the peeling device is automatically moved, the rotational resistance of the rotating member is detected. To detect rotational resistance, for example,
(1) Detect the current of the drive motor,
(2) Detecting the rotation speed of the leading roller,
(3) Detect the rotation speed ratio or difference between the driving roller and the tip roller.
It depends on the method.
FIG. 18 shows an example of change in rotational resistance, with time on the horizontal axis and rotational resistance on the vertical axis. In this way, the rotation resistance is detected, and the contact state between the first rotation member and the sticking member M and the peeled state of the tip can be detected from the rotation resistance. And the moving means for moving the peeling device can be controlled.
Moreover, also when the sticking member M is cut | disconnected in the middle, it can detect from the change of rotational resistance. Using the relationship between the moving speed of the peeling device and the cutting rate, the moving means can be controlled to an appropriate speed.
